I just recieved this shorts/shirt duo - it's meant to be a birthday gift for my soon to be four year old grandson. So, at this point, I can only estimate the actual fit, but I'm impressed with the overall quality and design. Both pieces appear to be well made from good fabric.
I believe the size I ordered (4) should be just right. My little grandson is small and thin for his age, so this outfit may even be a little large on him. Not a problem - the tee shirt style and elastic waist/drawstring of the shorts should readily accommodatee variations in height and weight.
I selected the navy blue top and white shorts option - both items can be easily mixed and matched with other pieces. The 'bug' prints on the shirt are bright, colorful and nicely detailed. The shorts are a true white - I wasn't certain of this from the product photo, so just an FYI... I would recommend this set and am very pleased with my purchase.
